JOSE-PH I. NIETERS, OF ST. LOUIS,- MISSOURI.

BRICK-PRESS.

lb all whom it may concern:

Be itknown that I, JOSEPH J. NIETERS, a citizen of the United States,residing at St. Louis, Missouri, have invented a certain new and usefulImprovem'ent in Brick-Presses, of which the following is a full, clearand exact description, suchas will enable othersskilled' in the art towhich it app'ertains-to make and use the same, reference being hadto theac-' companying drawings, formlng part of this specification, in which IFigure 1 is a'front elevation of a brick press constructed in accordancewith my inventio Fig. 2 is aside elevation of said rna- 3 is a verticalsectional view showing't e chargirw device in its-forw, rd osition afterit has filled the mold box with cay; Fig; 4 is a transverse sectionalview throu h the hopper;-and Fig. 5 is a vievnsimichine lar to 'ig. 3but with the parts in a different havinfg -vice r keeping the faces ofsome 0 the mold members and also other parts of the machine lubricated.1

Another object is to provide a novel form ofdevice for grinding up clayfromwhich the bricks are formed while the clay is in the hopper of themachine; and still another ebject of my invention is to provide ahandpower brick press which is of simple construction and can beoperated easily.

Other desirable features of my invention will be hereinafter pointedout.

Referring to the drawings which represent the preferred form of myinvention, 1 desig- Hates the hopper of the machine into which the clayis thrown, the clay being in its naturalcondition just as it is takenfrom the bank. The mold box 2 is arranged below the hopper and slightlyin front of same, and extending rearwardly from the mold box is a table3 on which the charging device 4 is reciprocatingly mounted. Thischarging do- Viee is provided at it's fronL end with an Specification ofLetters @atent Application filed March 12. 1907. emu No. 361.973.

opening 5 into which some of the clay in the hopper drops when thecharging device is in its rearward position, as shown in Fig. 5, saidcharging device being moved from its rearward into it's forwardposition, as shown in Fig. 3, to permit the clay to drop into the moldbox.- A lower lunger 6 reciprocates in the mold box, and arranged abovethe mold box and in alinement therewith, is an impel-(plunger 7, theseplungers being moved tower /each other to com rose the mass of clay inthe mold box and t us form a brick, as shown in Fig. 5. After the brickhas been formed the upper plungerandthe lower plunger both move upwardlyso as to carry the brick out of the mold box, the charging device 4having previously been moved into its rearward position so that thefront end thereof is located at the rear of the brick. When saidcharging device moves forwardly to carry a fresh char e of clay to themold box the front, end of t e chargmg device will engage the brickwhich at this time is en ported on the lower plunger flush with tie topof the mold box, and will ejlect said brick onto an ehdless conveyer orbe t 8 extending forwardly from the maohine and having its upper surfacearran cd-in the same horizontal plane as the tab e 3.' This endlessconveyer is moved intermittently so that after a brick has beendeposited thereon the next brick that is moved onto said conveyor willnot-contactwith the brick that was previously laced on same, therebypreventing the brie s from rubbing against each other or marrmg thesurfaces and .thus spoilin thereof as would lie apt to result dueto thefact that when the bricks are ejected from the mold box they are verymoist'and comparatively soft. i

In order that the bottom face of the upper plunger 7 may be keptthoroughly lubricated and also the sides of the mold box and the uppersurface of the table 3 on which the charging device reciprocatvs, I have)rovided the )ress with an oiling device W ich consists of clampedbetween the front end of the charging device and a bar 10 that issecuredthereto by means of bolts or in any suitable manner, the upper end of 1his piccc of fibrous material projecting above the upper edge of thecharging device so that it will'contact with the underneath face of theupper pluna piece of fibrous material 9 material 9 and thus satiii-sting with oil, the upper edge of ths fibrous pieos 9 sppiyw .ingthe oil to the bottom of the upper piunge'r', and ths Laws-edge oiplying the oil to i sids of the modhozi: 0i" rather to the upper of thesash ox so: oii ass flow downtho .ie faces tool-oi sndioss i 8 ontowhich the sis- 111* o fsd th *"eti from L box travels o mounts v x.

The normal position of the lower plunger can bevaried by means of an adjustable contact screw 36 mounted machine and aapted to contact with the inclined lower face at the inner end of theoscillating member 25. i

The die late 37'which forms the pressing face of the ower plunger, isalso of novel con struction in that its engaging face is perfectlysmooth, said plate being provided on its underneath side with a screwwhich extends through an opening in the top of the plunger and has a nut38 mounted thereon to secure said plate in position. In the machines ingdevices that secured the die plates to the longer extended clear throughto the pressmg faces of said lates so that these fastening devices wou dleave their imprint on the brick.

In order that clay in its natural state may be usedin the machine I haveprovided the hopper with means for grinding up or pulverizing the clay,this means consisting of transversely extending grate-bars 40 over whicha rotary kniie carrying member travels. This rotary knife-carryingmember versely of the hop er, the arms of said spiders havin knife blates 43 secured thereto. A knife blade 44 is connected to arms 45 that areloosely mounted on the shaft 42, these arms being of less length thanthose of the spider so that the knife blade 44 will be located withinthe circular mth in which the knife blades 43 travel. This knife blade44 coo crates 'with those connccted to the s i ers 41 and thus forms ashearing device that acts to cut the clay up very line, the knife blades43 also cooperating with the grate-bars to sever and grind up the clayin the hop er.

i. The sliaft 42 is rotated bymeans of belts or ropes 46 secured to thelovers 21 and wound around rooved pulleys 47 on the opposite ends of theshaft 42, a weight 48 being secured to the end of each of said belts soas tion and also rotate the knife-carrying membar in the oppositedirection to that in which it is rotated when the lovers 21 aredepressed.
